The InfoSource Implementation and Costing Data (PS) provides the data on the implementation phase for Easy Cost Planning (ECP) in the Project System (PS).

Approved appropriation requests are transferred to PS and from this point on are only accessible via the master data on the WBS element.

The costing data in ECP is determined without cumulation levels, since summation takes place in BW itself. Since it is possible to build a hierarchical structure of cost estimates, costing items and sub cost estimates in ECP, only the “nodes” of each costing tree are determined. The costing hierarchy can contain any number of levels. A cost estimate contains a header record and lower-level costing items. A costing item can reference a further sub cost estimate, which itself can contain several items. If a sub cost estimate exists for a costing item, the costing item contains a reference to the cost estimate created for this purpose. Sub cost estimates are created as new cost estimates with a separate item category. The initial item from which the sub cost estimate is created represents the total from all lower-level items.

ECP does not provide delta functionality, which means that the system always extracts all current cost estimates. A delta can therefore only be represented as an unspecified delta using BW.

Each costing number comes from a costing model. All items in a cost estimate use the same model. Characteristics and their attributes on which these models are based are provided as master data and are also available in the media title (0ME_PLMTITL characteristic). The same applies to the costing hierarchy for costing items (0ME_CALPOS characteristic).
